Initial configuration

Apache Geronimo provides a couple of configuration files where you can edit some of the parameters before starting the server. Look into the following topics for more details.

Changing the default port numbers — The config-substitutions.properties file lets you specify a totally new set of ports and define an automatic port offset for when you run multiple servers (or instances of the same server).

Changing the username and password — The default administration user name and password for the Geronimo Administrative Console and command line deployment tool is system and manager respectively. You can change these defaults

Substituting one module with another — You may want to change the version of jars or plugins from those used when your Geronimo server was assembled, or completely replace one with another.

Additional configuration changes can be made on the config.xml file available in the <geronimo_home>/var/config/ directory.
